TECHNICAL FIELD

The present disclosure relates generally to the field of multicomputer data transferring. More specifically, and without limitation, this disclosure relates to systems and methods for using multicomputer data transferring to provide contactless communication.

BACKGROUND

Contactless technologies, such as radio frequency identification (RFID), near field communication (NFC), and the like, are often used in transportation systems, hotel rooms, and other systems. However, such systems use different contactless cards or require different applications executed on mobile phones or other mobile devices to interact with different systems.

Moreover, contactless systems are often activated manually. For example, a user may use a website to activate a contactless card, may use a kiosk to activate a contactless card or mobile phone application, or may otherwise manually activate a particular card or device for use on a particular system.

DETAILED DESCRIPTION

The disclosed embodiments relate to systems and methods for backing up a distributed database on a cloud service that provide the distributed database within a geographical region. Embodiments of the present disclosure may be implemented using a general-purpose computer. Alternatively, a special-purpose computer may be built according to embodiments of the present disclosure using suitable logic elements.

Advantageously, disclosed embodiments may solve the technical problem of porting a contactless device, such as a card or a mobile phone, across a plurality of contactless systems. Moreover, disclosed embodiments may solve the technical problem of automating the previously manual process of activating contactless devices when necessary. Therefore, the disclosed embodiments enable a single contactless device to seamlessly and automatically port across multiple contactless systems and in different situations (such as in a transit system, a hotel, or the like) in response to authorization of a transaction related to said contactless system.

FIG. 1 depicts a block diagram of a system 100 for using multicomputer data transferring to activate a contactless device. As illustrated in FIG. 1, system 100 may include a device 101 that sends a transaction through network 105 to account server 107. Network 105 may comprise an open loop network (e.g., the Internet, a cellular network, or the like) or a closed loop network (e.g., an intranet, leased link network, or the like). For example, device 101 may comprise a point of sale system, a website, or any other device sending a transaction for approval. Account server 107 may comprise a server associated with a financial institution or other server storing account records. Account server 107 may authorize the transaction. Although depicted as received directly from device 101, the transaction may be received from a payment processor forwarding the transaction from device 101 to account server 107.

As further depicted in FIG. 1, system 100 may include a merchant server 109 that sends an access code through network 105 to contactless device 103. Contactless device 103 may comprise a mobile device (e.g., device 700 of FIGS. 7A and 7B) or a card (e.g., card 800 of FIG. 8). For example, the access code may be transmitted by contactless device 103 to authorize it for use in contactless reader 111. Alternatively, merchant server 109 may transmit the access code to account server 107 for transmission to contactless device 103.

In some embodiments, contactless device 103 may include a fixed identifier or access code rather than re-configuring in response to a transmission from merchant server 109 or any other external device. Accordingly, merchant server 109 may configure contactless reader 111, as explained below, such that contactless device 103 is recognized and authorized by contactless reader 111 without any transmission being sent to contactless device 103.

As further depicted in FIG. 1, merchant server 109 may transmit an identifier of contactless device 103 through network 105 to contactless reader device 111. Contactless reader 111 may comprise a kiosk, an RFID reader, or other device including at least one coil to transmit radio signals at a frequency (e.g., determined by RFID standards, NFC standards, Bluetooth standards, or the like) and/or receive radio signals from contactless device 103. In addition to the at least one coil, contactless reader 111 may include a microprocessor, a processor, or other circuit controlling intensity, timing, and/or other properties of the radio signals transmitted by the at least one coil and may include a network interface controller or other network communicator to send and receive data to and from a remote server in the same contactless network as reader 111.

In some embodiments, the identifier may comprise a serial number of contactless device 103, a serial number of a component of contactless device 103 (such as a transponder, a printed circuit board, or other component of contactless device 103), a machine name associated with contactless device 103, or the like. Contactless reader 111 may thus respond to contactless device 103. In some embodiments, merchant server 109 may additionally or alternatively transmit the access code to contactless reader 111. Accordingly, if contactless device 103 transmits the access code to contactless reader 111, contactless reader 111 may respond accordingly, e.g., by allowing access to a corresponding transit system, hotel room, or the like.

In some embodiments, the access code may be associated with a period of time. Accordingly, contactless device 103 may be authorized to communicate with contactless reader 111 only during the period of time. For example, the access code may be associated with a flight reservation such that contactless reader 111 accepts the access code only during boarding of the flight. In another example, the access code may be associated with a hotel reservation such that contactless reader 111 accepts the access code only during the reservation.

Additionally or alternatively, the access code may be associated with a number of uses. Accordingly, contactless device 103 may be authorized to communicate with contactless reader 111 for a predetermined number of times. For example, the access code may be associated with an amusement park such that contactless reader 111 accepts the access code for a number of rides that have been purchased and then rejects further uses. In another example, the access code may be associated with.

Additionally or alternatively, contactless device 103 may be authorized for the period of time and/or for the number of uses without receiving an access code. For example, as described above, contactless reader 111 may receive instructions to authorize contactless device 103 for the period of time and/or for the number of uses without requiring contactless device 103 to produce an access code.

Account server 107 may comprise one or more servers operated by an institution authorizing the transaction, and merchant server 109 may comprise one or more servers operated by an operator of the contactless network including contactless reader 111. Additionally or alternatively, merchant server 109 may comprise one or more servers operated by a third party managing the contactless network associated with the merchant.

Account server 107 and merchant server 109 may use multicomputer data transferring such that contactless device 103 is authorized automatically when the transaction is authorized. For example, account server 107 may determine an associated merchant based on the transaction to determine merchant server 109 for receipt of a data packet, e.g., using a database linking merchants to server locations (e.g., Internet Protocol (IP) addresses or the like).

Account server 107 may send a data packet (e.g., an application programming interface (API) call) to merchant server 109 in response to the transaction. For example, account server 107 may determine that the transaction is associated with a merchant having a contactless network, such as a hotel, an airline, a transit system, or the like. Accordingly, account server 107 may send a data packet to authorize contactless device 103 to interact with contactless reader 111 of the contactless network. By using multicomputer data transferring accordingly, account server 107 may allow a user to port contactless device 103 to different contactless networks and to port contactless device 103 automatically in response to a transaction.

FIG. 2 shows a block diagram of a multicomputer exchange 200 between two servers to authorize a contactless device. For example, exchange 200 may be effected using method 300 of FIG. 3, method 400 of FIG. 4, or a combination thereof. One of ordinary skill will understand that the arrangement of FIG. 2 is exemplary; other arrangements may be used to perform the same functions as described herein. Contactless device 201 may comprise, for example, user device 700 of FIGS. 7A and 7B or card 800 of FIG. 8. Similarly, servers 203 and 223 may comprise account servers 107 and merchant server 109, respectively, of FIG. 1.

As depicted in FIG. 2, contactless device 201 may include a transponder 207 and a wireless communications device, e.g., network interface controller (NIC) 205. Correspondingly, reader device 233 may include a transponder 239, a processor 235, and a network controller 237. Accordingly, transponder 207 may communicate with transponder 239 using radio signals, e.g., using RFID protocols, NFC protocols, or the like.

As further depicted in FIG. 2, processor 217 of server 203 may, in response to a transaction, retrieve an identifier of server 223 from merchant database 219. Merchant database 219 may map merchants (e.g., included in the transaction) to locations of servers associated with the merchants (e.g., IP addresses, machine names, or the like). Accordingly, merchant database 219 may comprise a relational database or the like.

Server 203 may use network controller 215 to transmit database packet 221 to server 223, which was identified based on merchant database 219. Data packet 221 may comprise an API call to server 223, as explained above with respect to FIG. 1.

In response to receiving data packet 221 using network controller 227, server 223 may retrieve an identifier of one or more contactless readers, e.g., reader device 233, using reader database 229. Reader database 229 may map properties of a transaction (e.g., identifier of a reserved room, identifier of a portion of a transit system, or the like) to corresponding locations of one or more contactless readers (e.g., IP addresses, machine names, or the like). Accordingly, reader database 229 may comprise a relational database or the like.

Server 223 may transmit an authorization 231 to reader device 233 and an access code 213 back to server 203 for transmission to contactless device 201. Alternatively, server 223 may transmit access code 213 directly to contactless device 201. Access code 213 may be transmitted by contactless device 201 to reader device 233 in order to authorize contactless device 201. As explained above with respect to FIG. 1, access code 213 may grant a limited time access to contactless device 201. Authorization 231 may comprise an identifier of contactless device 201, a corresponding code to access code 213, or other data by which reader device 233 may verify contactless device 201.

As further depicted in FIG. 2, contactless device 201 may transmit access code 213 to reader device 233 such that contactless device 201 is granted access to at least a portion of a contactless network (e.g., a transit system, a hotel room, or the like) associated with reader device 233. In the example of FIG. 1, contactless device 201 transmits access code 213 in response to an inquiry 241 from reader device 233. Alternatively, contactless device 201 may transmit access code 213 in response to user input to contactless device 201. In an alternative example, reader device 233 may transmit inquiry 241 and contactless device 201 may transmit an identifier of itself in response. Reader device 233 may therefore verify contactless device 201 using authorization 231 and the identifier of contactless device 201.

FIG. 3 depicts an example method 300 for using multicomputer data transferring to activate a contactless device. Method 300 may be implemented using one or more processors (e.g., processor 601 of FIG. 6).

At step 301, the processor may receive a transaction associated with a merchant on a list of merchants stored in the at least one memory. For example, as explained above with respect to FIG. 1, the processor may receive the transaction from a point of sale device, a website, or the like. In some embodiments, as explained above with respect to FIG. 2, the list of merchants may comprise a database linking merchant identifiers to identifiers of remote servers associated with merchants.

At step 303, the processor may determine, based on the merchant, a remote server (e.g., server 109 of FIG. 1) associated with the merchant. For example, the processor may use the database to determine an IP address, machine name, or other identifier of the remote server associated with the merchant.

At step 305, the processor may assemble a data packet including an identifier of the contactless device and an identifier of the transaction. For example, the data packet may comprise an application programming interface (API) call to an application executed by the determined server.

The identifier of the contactless mobile device may comprise at least one of a serial number of a component of the contactless mobile device, or a universally unique identifier (UUID) associated with the contactless mobile device. Additionally or alternatively, the identifier of the transaction may comprise at least one of an identifier generated by the at least one processor, an identifier generated by the merchant, or a reservation number associated with the transaction.

At step 307, the processor may transmit the data packet to the determined server across one or more computer networks. For example, the processor may use Wi-Fi, a 4G, a long-term evolution (LTE), or other protocol across a local area network (LAN), the Internet, or other computer network.

At step 309, the processor may receive confirmation from the determined sever (e.g., server 109 of FIG. 1) in response to the data packet. For example, the confirmation may comprise confirmation that the determined server authorized the contactless device.

At step 311, the processor may transmit the confirmation to a user device (e.g., sale device 101 and/or contactless device 103 of FIG. 1) associated with the transaction. For example, the confirmation may comprise a push alert or other message to the user device indicating that the determined server authorized the contactless device.

In embodiments where the contactless device comprises a contactless mobile device, the processor may transmit the confirmation to the contactless mobile device. In such embodiments, transmitting the confirmation may comprise transmitting an application programming interface (API) call to an application executed by the contactless mobile device. The API call may be configured to modify one or more settings of the contactless mobile device. The modified settings may be configured to authorize the contactless mobile device to communicate with one or more reader devices associated with the merchant.

Method 300 may further include additional steps. For example, method 300 may further include transmitting credentials to the determined server. In some embodiment, the credentials may comprise credentials associated with a purchaser of the transaction or an authorization previously provided from the determined server.

In some embodiments, the processor may be prompted for the credentials. For example, the processor may receive a request for credentials from the determined server and, in response to the request, transmit credentials to determined server to authenticate the system.

In any of the embodiments described above, the processor may receive an access code from the determined server and transmit the access code to the contactless device. For example, the processor may transmit the access code across one or more computer networks to a contactless mobile device. In another example, the processor may transmit the access code across one or more computer networks to the user device associated with the transaction. The user device may then forward the access code to the contactless device, such as a contactless card associated with the user device.

FIG. 4 depicts an example method 400 for using multicomputer data transferring to activate a contactless device. Method 400 may be implemented using one or more processors (e.g., processor 601 of FIG. 6). Method 400 may represent a method corresponding to method 300, described above. For example, method 300 may be executed by one server and method 400 executed by another server to perform a multicomputer data transfer to activate a contactless device.

At step 401, the processor may receive, from a remote server (e.g., account server 107 of FIG. 1), an identifier of a transaction and an identifier of a contactless device (e.g., contactless device 103 of FIG. 1). For example, the processor may receive data packet 221 of FIG. 2, explained above.

At step 403, the processor may retrieve a period of time associated with the transaction. For example, the processor may use a transaction ID, a reservation number, or other identifier included in the transaction identifier to retrieve information related to the transaction from a reservation database. For example, the processor may access a hotel reservation having a reservation period associated therewith, an airline reservation having a boarding time associated therewith, or the like.

At step 405, the processor may verify that the contactless device is associated with the transaction. For example, the processor may determine whether a name associated with the contactless device matches a name listed on the transaction (or included in the reservation associated with the transaction).

At step 407, the processor may transmit a command to one or more remote readers to authorize the contactless device during the period of time. For example, the command may comprise an API call to an application executed by the one or more remote readers to authorize the contactless device. Additionally or alternatively, the command may include an identifier of the contactless device, an access code, or the like, such that the one or more remote readers may verify the identity of the contactless device.

At step 409, the processor may transmit confirmation to the remote server. For example, the confirmation may comprise confirmation that the contactless device is authorized.

Method 400 may further include additional steps. For example, method 400 may include a transmitting request for credentials to the remote server (e.g., account server 107 of FIG. 1) and, in response to the request, receiving credentials from the remote server to authenticate the remote server. In some embodiments, the processor may perform verification and transmit the command only after the remote server is authenticated.

In any of the embodiments described above, the processor may transmit the access code to the contactless device or to the remote server for forwarding to the contactless device. Accordingly, the command may configure the one or more readers such that, when the contactless device transmits the access code, the one or more readers may verify the contactless device during the period of time.

FIG. 5 depicts an example method 500 for activating a contactless device. Method 500 may be implemented using a contactless device (e.g., device 700 of FIGS. 7A and 7B or card 800 of FIG. 8). Method 500 may represent a method corresponding to method 400, described above. For example, method 500 may be executed in response to method 400 being executed by the remote server.

At step 501, using a wireless communicator, the contactless device may receive, from a remote device, an access code associated with a period of time associated with a transaction. For example, the access code may comprise a digital code, and the contactless device may encode the digital code as intensity and timing of a radio frequency signal. Alternatively, the access code may have been previously encoded as intensity and timing of a radio frequency signal before receipt by the wireless communicator.

As explained above, the access code may authorize the contactless device to a contactless reader for the period of time. The contactless reader may be in a contactless network operated by a merchant of the transaction.

At step 503, using a control circuit, the contactless device may set a content of a radio frequency signal transmitted by a contactless card. For example, the control circuit may set intensity and timing of the radio frequency signal based on the access code. Additionally or alternatively, the control circuit may set the content using existing radio frequency standards, such as RFID, NFC, or the like. As explained below with respect to FIG. 8, the control circuit may comprise a clock circuit, a microprocessor, or other circuit controlling properties of the radio frequency signal.

At step 505, using a transponder, the contactless device may transmit the radio frequency signal to a reader device. For example, the radio frequency signal may have the intensity and timing previously set by the control device.

At step 507, when the period of time expires, the contactless device may use the control circuit to reset the content of the radio frequency signal. Additionally or alternatively, the access code may be associated with a number of uses, and step 507 may be executed after the number of uses have been met. In some embodiments, step 507 may be omitted such that the contactless card is not modified until another control signal is received to set the intensity and timing of the radio frequency signal.

FIG. 6 is block diagram of an example device 600 suitable for implementing the disclosed systems and methods. For example, device 600 may comprise a server that executes method 300 of FIG. 3 and/or method 400 of FIG. 4.

As depicted in FIG. 6, server 600 may have a processor 601. Processor 601 may comprise a single processor or a plurality of processors. For example, processor 601 may comprise a CPU, a GPU, a reconfigurable array (e.g., an FPGA or other ASIC), or the like.

Processor 601 may be in operable connection with a memory 603, an input/output module 605, and a network interface controller (NIC) 607. Memory 603 may comprise a single memory or a plurality of memories. In addition, memory 603 may comprise volatile memory, non-volatile memory, or a combination thereof. As depicted in FIG. 6, memory 603 may store one or more operating systems 609 and program instructions for multicomputer transferring 611. For example, instructions 611 may cause server 600 to execute method 300 of FIG. 3 and/or method 400 of FIG. 4. In addition, memory 603 may store data 613 produced by, associated with, or otherwise unrelated to operating system 609 and/or instructions for multicomputer transferring 611.

Input/output module 605 may store and retrieve data from one or more databases 615. For example, database(s) 615 may include a database storing merchant identifiers with corresponding identifiers of remote servers operated by merchants.

NIC 607 may connect server 600 to one or more computer networks. In the example of FIG. 6, NIC 607 connects server 600 to the Internet. Server 600 may receive data and instructions over a network using NIC 607 and may transmit data and instructions over a network using NIC 607.

Each of the above identified instructions and applications may correspond to a set of instructions for performing one or more functions described above. These instructions need not be implemented as separate software programs, procedures, or modules. Disclosed memories may include additional instructions or fewer instructions. Furthermore, server 600 may execute method 300 of FIG. 3 and/or method 400 of FIG. 4. These functions of the user device and/or server 600 may be implemented in hardware and/or in software, including in one or more signal processing and/or application specific integrated circuits.

FIG. 7A is a depiction of exemplary user device 700 for use as a contactless device. As depicted in FIG. 7A, device 700 may comprise a smartphone. Device 700 may have a screen 701. For example, screen 701 may display one or more GUIs that allow a user to enter input activating contactless communication. In certain aspects, screen 701 may comprise a touchscreen to facilitate use of the one or more GUIs.

As further depicted in FIG. 7A, device 700 may have one or more buttons, e.g., buttons 703 a and 703 b. For example, buttons 703 a and 703 b may facilitate use of one or more GUIs displayed on screen 701.

FIG. 7B is a side view of device 700 of FIG. 7A. As depicted in FIG. 7B, device 700 may have at least one processor 705. For example, at least one processor 705 may comprise a system-on-a-chip (SOC) adapted for use in a portable device, such as device 700. Alternatively or concurrently, at least one processor 705 may comprise any other type(s) of processor.

As further depicted in FIG. 7B, device 700 may have one or more memories, e.g., memories 707 a and 707 b. In certain aspects, some of the one or more memories, e.g., memory 707 a, may comprise a volatile memory. In such aspects, memory 707 a, for example, may store one or more applications (or “apps”) for execution on at least one processor 705. For example, an app may include an operating system for device 700 and/or an app for executing method 500 of FIG. 5. In addition, memory 707 a may store data generated by, associated with, or otherwise unrelated to an app in memory 707 a.

Alternatively or concurrently, some of the one or more memories, e.g., memory 707 b, may comprise a non-volatile memory. In such aspects, memory 707 b, for example, may store one or more applications (or “apps”) for execution on at least one processor 705. For example, as discussed above, an app may include an operating system for device 700 and/or an app for executing method 500 of FIG. 5. In addition, memory 707 b may store data generated by, associated with, or otherwise unrelated to an app in memory 707 b. Furthermore, memory 707 b may include a pagefile, swap partition, or other allocation of storage to allow for the use of memory 707 b as a substitute for a volatile memory if, for example, memory 707 a is full or nearing capacity.

As further depicted in FIG. 7B, device 700 may include at least one coil 709. Coil 709 may be used for contactless communication, e.g., RFID, NFC, or the like. Although not depicted in FIG. 7B, device 700 may further include a wireless communicator for connecting device 700 to one or more computer networks. For example, device 700 may receive data and instructions over a network using an NIC and may transmit data and instructions over a network using the NIC.

Although depicted as a smart phone, device 700 may alternatively comprise a tablet or other computing device having similar components.

FIG. 8 is depiction of exemplary contactless card 800 authorized by multicomputer data transferring. As depicted in FIG. 8, device 800 may include a transponder 801, a control circuit 803, and a wireless communicator 807. In some embodiments, device 800 may include a battery 805 to power transponder 801, control circuit 803, and wireless communicator 807. Alternatively, transponder 801 and control circuit 803 may be powered by an incoming radio frequency signal and/or wireless communicator 807 and control circuit 803 may be powered by an incoming control signal.

As further depicted in FIG. 8, control circuit 803 may comprise a microprocessor or any other circuit controlling the content transmitted by transponder 801. For example, control circuit 803 may control timing, intensity, or other properties of a radio frequency signal transmitted by transponder 801.
